changes in different regions of the lungs. my fev1 was 88.5%. Peak flow rate was 6.09 and tlc was 5.79. I don't know what they are now, I've had many chest infections and I know my breathing is so much worse. Earlier this year with a very nasty c/h I had an ordinary x ray and was diagnosed with Bronchiectasis. I don't know if the tests I had 6 years ago were good, so could it be that it will be some time yet before these readings get worse? I have to say that until the last Chest infection I was not too bad, I could recover pretty well from previous c/i's but not this time, this one has really taken it's toll on me.
